T1 is a Union transit procedure run through the NCTS system, which suspends the collection of duty and VAT until the transit is closed at the office of destination. Direct import, on the other hand, means releasing the goods for free circulation and paying the customs charges already at the point of entry, with no transit stage.

How to prepare the process and documents
The scope of responsibility of the parties
When it comes to the difference between T1 and direct import, it's essential to distinguish the responsibility between the importer, the exporter and the customs representative, since this determines the scope of data submitted to the official systems. Under T1 transit, the main party liable is the principal — the entity that lodged the transit guarantee and is responsible for delivering the goods to the office of destination. Under direct import, responsibility rests with the importer or their representative from the moment the border is crossed.
The minimum data set for the declaration
For the T1 procedure you need: the MRN, the guarantor's details, the office of departure and destination, the CN commodity code, gross and net weight, and the transport details. For direct import, you also need: the customs value confirmed by the invoice, the country of origin, preferential documents (if used), and the importer's EORI number. The completeness of the data set should be checked before the declaration is submitted — gaps at this stage result in the declaration being rejected and the release of the goods being delayed.

How the declaration and inspection work
The operational stages from notification to release
The most common risk points and how to reduce them
An internal checklist linking documentation requirements to the responsibilities of the logistics team, accounting, and the person responsible for compliance makes it possible to eliminate the most common operational errors. Under T1 transit, the main risk is failing to close the procedure within the set deadline — this risks the guarantee being activated and a customs debt falling on the principal. Under direct import, the most common problem is an incorrect tariff classification resulting in underpaid duty or VAT, which the authorities detect during a post-clearance audit.
How to maintain compliance and settlements
Archiving, amendments and evidence of due diligence
Customs documentation — for both T1 and direct import — should be kept for at least 5 years from the date the declaration was accepted. Amendments to a declaration are permitted before the goods are released; after release, an appeal or a request for revision is required. Evidence of due diligence includes a written verification of the goods' classification, a documented transaction value, and an archive of correspondence with the customs authority.
Working with a customs agency and internal audit
An external customs agency acting as an indirect or direct customs representative takes on part of the responsibility for the correctness of the declaration, but this does not relieve the importer of the duty to verify the data provided. An internal audit should include, at minimum, a quarterly review of closed T1 procedures for timely closure, and a review of import decisions for consistency of tariff classification and declared customs value.
Summary
In summary: when it comes to the difference between T1 and direct import, what matters most is running the process according to current official guidance, with a clear split of responsibility and documentation of every decision. T1 transit requires particular attention to closing the procedure on time and managing the guarantee, while direct import requires precision in tariff classification and customs value. This approach reduces delays, cuts down on corrections, and makes it easier to defend your settlements during an inspection. If any requirement is unclear, check the current KAS notices or contact a customs agency holding Authorised Economic Operator (AEO) status.

Frequently asked questions
What's the main difference between the T1 procedure and direct import?
The T1 procedure (Community customs transit) allows goods to be moved across a customs territory with charges suspended — duty and VAT are not collected in every country the goods pass through, but only once the transit has been closed at the office of destination. Direct import means the goods are released for free circulation immediately after crossing the border, with all customs and tax charges paid at the same time. The choice between these procedures depends on the transport route, the customs status of the goods, and the structure of the supply chain.
Who is responsible for closing the T1 procedure, and what happens if the deadline is missed?
Responsibility for closing T1 transit lies with the principal — the entity that lodged the transit guarantee and opened the procedure at the office of departure. Failing to close the transit within the set deadline triggers an enquiry procedure, followed by activation of the guarantee and the assessment of a customs debt covering duty, VAT and interest. That's why monitoring the status of the MRN after every movement is an operational obligation, not an option.
What documents are required for a direct import from the United Kingdom into Poland?
For a direct import from the UK into Poland you need: a commercial invoice showing the transaction value, a packing list, a transport document (CMR, bill of lading or AWB), a statement on invoice or an EUR.1 certificate confirming preferential origin (if the goods qualify under the TCA), the importer's EORI number, and — depending on the category of goods — additional sanitary, phytosanitary permits or licences.
Is a customs agency liable for errors in a customs declaration?
A customs agency acting as a direct customs representative is jointly liable with the importer for the accuracy of the data in the declaration. Under indirect representation, the agency is liable independently to the customs authority. Regardless of the form of representation, the importer is required to provide complete and accurate data — errors resulting from incorrect information given to the agency fall on the importer. Written confirmation of the key data before the declaration is submitted is the standard of due diligence.
When is it worth choosing T1 instead of direct import, and vice versa?
T1 is optimal when the goods are moved in transit through several customs countries before reaching their final destination — this avoids repeated clearance, and suspending the charges reduces cash-flow risk. Direct import is more advantageous when the goods enter circulation immediately after crossing the border, the importer holds AEO status and can use simplified procedures, or when the value of a transit guarantee would be disproportionately high relative to the value of the goods.
